Did you know? Toddlers have better hearing than adults

Most of us might assume that as we get older, our senses get more refined. But in matters of hearing, this is frequently not the case. According to research, toddlers—those inquisitive and active world travellers—really have superior hearing than adults. This phenomena emphasises the significance of comprehending how our senses change over time, in addition to the fascinating features of human evolution.

The Science Behind Toddlers’ Superior Hearing

The ability of toddlers to hear better than adults is backed by scientific research. According to Dr. Patricia Kuhl, a professor of Speech and Hearing Sciences at the University of Washington, “Young children have incredibly sensitive hearing abilities. They can detect a wider range of frequencies than adults, making them more attuned to subtle sounds.”

She brought attention to this during her “The Linguistic Genius of Babies” TED Talk, in which she talked about how infants are more sensitive to sounds.

Toddlers benefit from this increased sensitivity in a number of ways, including language acquisition, voice recognition, and improved surroundings awareness.

A toddler’s auditory system is still developing, therefore a wider variety of noises can be perceived by it. Hair cells in the cochlea, the portion of the inner ear that transforms sound waves into electrical signals for the brain, are more densely packed in newborns and early children. Our ageing process can cause damage or loss of some of these hair cells, impairing our ability to hear high-frequency noises. Often occurring gradually and not becoming apparent till later in life, but the process begins surprisingly early.

A Critical Window for Language Development

The superior hearing ability of toddlers is not just a biological curiosity; it has profound implications for their cognitive and linguistic development. According to Dr. Nina Kraus, a neuroscientist and professor at Northwestern University, “The early years are crucial for language development because the brain is especially plastic and receptive to learning.”

Toddlers can discriminate between minute changes in sounds that adults may no longer notice because of the plasticity of their developing brains.

Since toddlers learn by imitating words and sounds they hear in their surroundings, this skill is essential to their language development. For instance, kids are able to distinguish between phonemes, which are a language’s fundamental units of sound and which adults may sound remarkably similar to. This sensitivity decreases with time as their brains grow increasingly specialised in the sounds of their mother tongue. For this reason, young children are better than adults in learning numerous languages.

What Does This Mean for Parents and Caregivers?

Parents, carers, and educators can all benefit from knowing that toddlers have greater hearing than adults. Toddlers are more susceptible to being overwhelmed by loud situations because of their increased sensitivity to sound. For a small toddler, a busy restaurant or packed mall may seem like an auditory attack. Toddlers can feel more confident and at ease if their surroundings are quiet and peaceful.

Experts advise parents to speak clearly and to steer clear of “baby talk” whenever feasible.Using a diverse range of intonations and a wide vocabulary when interacting with youngsters can foster their language development. Toddlers are more sensitive to the subtleties of speech since they are more developed than adults in terms of hearing and distinguishing sounds, which makes these interactions quite beneficial for their development.

The Gradual Decline of Hearing Sensitivity

Our capacity to hear high frequencies steadily deteriorates with ageing. Everyone is impacted by this presbycusis process, albeit to differing degrees. Certain drugs, genetics, and loud noise exposure can all hasten the deterioration of hearing. It is important to remember, though, that this aging-related natural decline is normal and usually does not affect day-to-day communication until much later in life.

Embracing the Wonders of Early Childhood

The remarkable capacities of the developing human body are demonstrated by the fact that toddlers have greater hearing than adults. The development of cognition and language acquisition are significantly influenced by this exceptional listening capacity. It serves as a reminder of how crucial it is to provide young children with environments that are encouraging of learning and discovery. Therefore, keep in mind that a toddler’s environment is full of sounds that we, as adults, may no longer fully enjoy the next time you find yourself in awe of a toddler’s seemingly endless energy and interest.

Parents and teachers can better assist the learning and development of young children and give them the best start in life by being aware of these special qualities.
